CA Health & Safety Code Section 118470

A permit to operate any business of laundering, sanitizing, or selling wiping rags shall be issued by the local health officer if the applicant complies with the provisions of this article and any regulations adopted thereunder. The governing body of each city and county shall determine the amount of any fee for the issuance of a permit pursuant to provisions of this article for any business within the territory under its jurisdiction. The amount of the fee shall not exceed the amount necessary to defray the costs of administering this article. The permit for operation shall be posted in a conspicuous place in the business establishment for which the permit is issued. Any permit issued pursuant to this article may be suspended or revoked for any violation of any of the provisions of this article, the regulations adopted thereunder, or any condition of the permit required by the ordinance of the local governing body. Nothing in this article shall preempt local regulation of the business of laundering, sanitizing, or selling wiping rags, and any local governing body may adopt an ordinance containing requirements more restrictive than those contained in regulations adopted pursuant to this article. The local health officer shall issue and serve upon the permit holder a notice setting forth in clear and concise language the act or omission upon which the violation is based, when the permit holder is charged with any violation and shall inform the permit holder of his or her rights to a hearing prior to suspension or revocation. At any time within the 15 days after service of the notice, the permit holder may request a hearing before the local health officer to show cause why his or her permit should not be suspended or revoked. A failure to request a hearing within 15 days shall be deemed a waiver of a right to a hearing. The local health officer may call a hearing for the purpose of investigating any violations of this article.
